How to Present Definite Numbers and Estimations

David Becker



By David Becker

Let’s take a look back at a classic guest post for our blog based on an article by Onwuegbuzie, Combs, Slate, & Frels (2010) that highlighted some of the most common APA Style errors. The number one mistake on that list is presenting numbers incorrectly. In this post, I'll be specifically focusing on how to properly present definite and estimated numbers.

Time

According to section 4.31e of the Publication Manual (p. 112), numerals are used to represent specific values that signify time, dates, ages, scores and points on a scale, exact sums of money, and numerals as numerals. For instance, one would write 5 days instead of five days. However, there is an exception to this rule: When referring to approximate units of time (e.g., weeks, days, months, and years), use words instead of numerals, as in about five days instead of about 5 days.

You may have noticed that this is a very specific exception. You may also be wondering whether this exception applies other approximate values. The short answer is no. This exception applies only to units of time—no such exceptions apply to any other approximate units of measure. However, keep in mind that precision and clarity are key to any form of writing, especially in the sciences, so always try to present definite numbers when possible.

For more information about writing numbers in APA Style, take a look at our series of posts on numbers and metrication and our FAQ page about when to express numbers as words.

How to Cite Multiple Pages From the Same Website

Timothy McAdoo

by Timothy McAdoo

Sometimes one's research relies on a very narrow thread of the World Wide Web.

What do I mean? We are sometimes asked how to cite multiple web pages from the same website. “Can’t I just cite the entire website?” our efficiency-minded readers ask. If you merely mention a website, yes.

But, if you quote or paraphrase information from individual pages on a website, create a unique reference for each one. This allows your reader to find your exact source. This may mean your reference list contains a number of references with similar, but distinct, URLs. That’s okay!

Laptop-filesLet’s look at an example:

Say you are writing a paper about Division 47 (Exercise and Sport Psychology) of the American Psychological Association (APA). In your paper, you begin by providing some background information about APA and about APA’s divisions, and then you provide more detailed information about Division 47 itself. In the process, you might quote or paraphrase from a number of pages on the APA website, and your reference list would include a unique reference for each.

American Psychological Association. (n.d.-a). Divisions. Retrieved from http://www.apa.org/about/division/
American Psychological Association. (n.d.-b). Exercise and Sport Psychology. Retrieved from http://www.apa.org/about/division/div47.aspx
American Psychological Association. (n.d.-c). For division leaders. Retrieved from http://www.apa.org/about/division/officers/index.aspx
American Psychological Association. (n.d.-d). For division members. Retrieved from http://www.apa.org/about/division/activities/index.aspx
American Psychological Association. (n.d.-e). Sample articles. Retrieved from http://www.apa.org/pubs/journals/spy/sample.aspx

It may seems a little unusual to have so many similar references, but in the context of this research topic, it makes perfect sense.

In-Text Citations

When you quote directly from a web page, be sure to include the paragraph number, in lieu of a page number, with the in-text citation. You may also include a paragraph number when paraphrasing. This will help readers locate the part of the page you are relying on.

Does APA Style Use Ibid.?

David Becker



By David Becker

Dear APA Style Experts,

Ibid Question

When should I use ibid. in my research paper? I want to cite the same source multiple times in a row, but I’m not sure how. Please help!

—Brann D.

Dear Brann,

Ibid. is one of several topics not covered in the Publication Manual because it isn’t used in APA Style. Other styles that document sources with footnotes or endnotes use ibid. to point to a source that was cited in a preceding note. APA Style, however, consistently uses the author–date format to identify an idea’s origin.

When repeatedly referring to the same source, it’s not always necessary to include a parenthetical citation at the end of every paraphrased sentence, as long as the narrative plainly indicates where the information is coming from. Even a direct quotation may not require a full parenthetical citation in this case—you can vary your citation style. If you’re not sure whether your paper clearly shows that you’re drawing multiple thoughts from one source, just ask your instructor, a classmate, or someone at your school’s writing center to give it a quick read. One of the most valuable resources in any form of writing is a second pair of eyes!

I hope this post answered your question, Brann! You can also turn to pages 174–175 of the Publication Manual for examples that show how to integrate citations into the narrative and when to include the publication date. Also be sure to check out one of our earlier posts that briefly reviews how to create in-text citations. And, as always, feel free to comment on this post, leave us a note on Twitter or Facebook, or contact us directly about any questions you may have.

Comparing MLA and APA: The Reference List

David Becker



By David Becker

Today, we continue with our series of posts highlighting some differences between APA and MLA reference styles. Last week, I outlined how the two styles handle in-text citations. Today’s post focuses on the reference list (or the “Works Cited” list as it is called in MLA Style). Below are examples of how each style would handle two common sources—a print book and a journal article from a research database. I have color coded the text to help you better visualize the differences in the basic elements of a generic reference. The who is in red, the when is in blue, the what is in yellow, and the where is in purple, all of which can be mixed and matched to form the Frankenreference.

Let’s begin with a print book, one of the simplest sources to cite:

MLA

Gordin, Michael D. The Pseudoscience Wars: Immanuel Velikovsky and the Birth of the Modern Fringe. Chicago: U Chicago P, 2012. Print.

APA

Gordin, M. D. (2012). The pseudoscience wars: Immanuel Velikovsky and the birth of the modern fringe. Chicago, IL: University of Chicago Press.

The two styles vary in a number of ways, including punctuation, capitalization, and placement of the date. Also, unlike APA Style, MLA Style includes the format of the source—either “Print” or “Web”—as an extra piece of “where” information, and it often requires writers to abbreviate publisher names.

Now let’s take a look at something a bit more complicated, a journal article from a research database:

MLA

Shafron, Gavin Ryan, and Mitchell P. Karno. “Heavy Metal Music and Emotional Dysphoria Among Listeners.” Psychology of Popular Media Culture 2.2 (2013): 74-85. PsycNET. Web. 11 Feb. 2014.

APA

Shafron, G. R., & Karno, M. P. (2013). Heavy metal music and emotional dysphoria among listeners. Psychology of Popular Media Culture, 2, 74–85. doi:10.1037/a0031722

The most substantive difference is that MLA Style requires the name of the database from which you retrieved the article and the date of retrieval as well; it does not use the DOI. In contrast, APA Style requires a DOI (when there is one), but doesn’t require the date of access (see p. 198 of the Publication Manual for more detail). In most cases, the name of the database is not used in an APA Style reference, although a few exceptions are outlined in Chapter 7.

Understanding Style

I hope this comparison of MLA and APA styles is helpful to those of you who find yourself transitioning from one to the other. If you are a student switching from MLA to APA, your most important resources will be the Publication Manual and this blog. I also recommend that you try our free tutorial on the basics of APA Style and visit our FAQ page, in addition to our pages on quick answers for citing sources and formatting your research paper.

Comparing MLA and APA: Citing Resources

DB2



By David Becker

Last week, we touched on the general differences between MLA and APA styles. Today, I talk about what is probably the biggest difference between the two styles: how to cite resources. These divergent rules can make transitioning from one style to the other a frustrating process, particularly for students. A few style errors can mean the difference between an A and a B on a paper. As an English major who only used MLA Style in school, learned APA Style for my job, and then relearned MLA Style for a few online courses, I can personally attest to the difficulty of mentally juggling two sets of style rules.

Style Frustration

Despite their differences, the APA and MLA citation systems have the same overall function in a research paper—sources are acknowledged via in-text citations, each of which corresponds to an entry in an alphabetical list of works at the end of the paper, referred to as “Works Cited” in MLA Style and “References” in APA Style. However, the MLA Handbook also mentions some variations, such as a “Works Consulted” list, which contains sources not cited within the body of the paper, and an annotated bibliography, which includes a brief description or evaluation of each source. APA Style does not use these alternate methods (see our posts about reference lists vs. bibliographies and some topics the Publication Manual doesn’t cover).

The differences between the two styles become even more apparent when one is creating text citations. MLA Style includes the author’s last name and the page number, whether citing a direct quotation or not. However, APA Style text citations also include the publication date, because the timeliness of research is important in science writing, and the page number is required only for direct quotations. Below are some hypothetical examples of parenthetical citations in both styles:

MLA

(Adams 42)
(Lennon and McCartney 999)
(Hexum, Martinez, and Sexton 123)

APA

(Adams, 1979) or (Adams, 1979, p. 42)
(Lennon & McCartney, 1968) or (Lennon & McCartney, 1968, p. 999)
(Hexum, Martinez, & Sexton, 1994) or (Hexum, Martinez, & Sexton, 1994, p. 123)

These citations lead readers to the reference list, which is where the differences between the two styles are most apparent, a topic I cover in my next post. In the meantime, I hope this overview has been helpful to those of you transitioning from MLA Style to APA Style. If you’re new to APA Style, the Publication Manual and this blog are your go-to resources. I also recommend that you try our free tutorial on the basics of APA Style and visit our FAQ page, as well as our pages that provide quick answers for citing sources and formatting your research paper.

Let Sleeping Dogs Lie (or Is It Lay?)

Daisiesby Stefanie

Here is my dog. Rooster_1
His name is Rooster. Rooster is a grammatical dog, and he is going to help me illustrate the difference between lay and lie.

Lay down, Rooster!

Rooster_1

 

Hmm, he doesn’t seem to have done anything. That’s because he’s waiting for me to tell him what to lay down. The verb lay requires a direct object, something that can be laid down (a toy, an egg, his spiffy bandana), but I didn’t specify, so he was right to wait for clarification.

 

 

 

OK, let’s try lie. Lie down, Rooster!  

Rooster_2Good boy! When I tell him to lie down, I’m telling him that he needs to get himself down. Now that he’s down, he’s snoozing away. I really am going to let a sleeping dog lie. (Consider the titular question answered!)

Now let’s change tenses to talk about what Rooster did. Here’s where the word choices get tricky. Laid is the past tense of lay; lay is the past tense of lie. So, When I told Rooster to lay down, he didn’t know what I wanted laid down. When I told Rooster to lie down, he lay down.

 

Finally, laid is the past participle form of lay, and lain is the past participle form of lie.

Rooster had laid his rawhide chew in the ivy patch at the corner of the house.

Rooster has lain there for a while; should I wake him up?

The next time you are debating whether to use lay or lie, it may help to picture the standing dog who is waiting for instructions on what he should lay down or the lying dog who obediently followed the order to lie down.

Footnotes for Source Citations in APA Style?

Jeffby Jeff Hume-Pratuch

Dear Style Experts,

I am writing a paper in APA Style. I have the sixth edition of the Publication Manual, but I’ve been unable to find instructions for how to format my citations in footnote form. All I see in the manual is examples of references. Can you help me? 
                                                                               —J. D. Scotus, Paris, TX

Dear J. D.,

There are a number of very good style manuals that use the footnote–bibliography method of citation, but the APA Publication Manual is not among them. APA Style uses text citations, not footnotes or endnotes, to direct the reader to a source in the reference list. This differs from other source documentation styles that use a combination of footnotes or endnotes and a bibliography for that purpose.

The only use for footnotes in APA Style is to provide additional content that supplements the text (e.g., to briefly acknowledge a tangential idea that is nevertheless important to the discussion or to note copyright permission for reprinting a lengthy quote). Endnotes are never used in APA Style, but you’ll find more about content footnotes in section 2.12 of the APA Publication Manual.

Dear Style Experts,

Author–date citations don’t give the reader enough information—I really prefer to give the source up front. What if I formatted the footnotes exactly like APA Style references, but put them at the bottom of the page? That would still be in APA Style, right? 
                                                                                         —J. D.

Dear J. D.,

The use of author–date text citations, rather than footnotes, is part of the essence of APA Style. It’s not optional.

Blueberry_heart_pancakesSuppose you asked me to make your favorite blueberry pancakes for Valentine’s Day. The store was out of blueberries, due to the latest snowpocalypse, so I used bananas; and the cat had gotten into the skillet, so I had to bake the batter in a muffin tin. The result might be delicious, but it wouldn’t be blueberry pancakes, would it? (Not even if we put maple syrup on them.)

Don’t put syrup on your muffins, and don’t use footnote citations in APA Style.

How to Cite References Containing Lead Authors With the Same Surname and Publication Date

Tyler

 

 

by Tyler Krupa

In a previous post, I provided guidelines on how to properly cite different groups of authors with the same lead author and publication date. As shown in that post, when you have two or more references of more than three surnames with the same year and they shorten to the same form (e.g., both Smith, Jones, Young, Brown, & Stanley, 2001, and Smith, Jones, Ward, Lee, & Stanley, 2001, shorten to Smith et al., 2001), you need to clarify which one you are citing each time. To do this, on the second and all subsequent citations, you should cite the surnames of the first two authors and of as many of the next authors as necessary to distinguish the two references, followed by a comma and et al. (see the sixth edition of the Publication Manual, p. 175).

Smith, Jones, Young, et al., 2001

Smith, Jones, Ward, et al., 2001

Now let’s add a twist and use references that contain different lead authors with the same surname and year of publication. Do you know what you should do differently? Let’s find out by looking at the following references:

Jones, B. T., Corbin, W., & Fromme, K. (2001). A review of expectancy theory and alcohol consumption. Addiction, 96, 57–72. http://dx.doi.org/10.1046/j.1360-0443.2001.961575.x

Jones, S. E., Oeltmann, J., Wilson, T. W., Brener, N. D., & Hill, C. V. (2001). Binge drinking among undergraduate college students in the United States: Implications for other substance use. Journal of American College Health, 50, 33–38. http://dx.doi.org/10.1080/07448480109595709

On the second and all subsequent citations, are you tempted to add the names of the additional authors to distinguish the two references? Although this seems like a logical way to proceed, because the lead authors are not the same person, you should instead include the lead author’s initials in all the text citations (for more information about when to use author initials for text citations, see my recent post). Therefore, the text cites for these two references would be as follows:

Correct:

First citation: Previous studies (e.g., B. T. Jones, Corbin, & Fromme, 2001; S. E. Jones, Oeltmann, Wilson, Brener, & Hill, 2001) have shown that . . .

Subsequent citations: Both B. T. Jones et al. (2001) and S. E. Jones et al. (2001) produced similar results . . .

Incorrect:

First citation: Previous studies (e.g., Jones, Corbin, & Fromme, 2001; Jones, Oeltmann, Wilson, Brener, & Hill, 2001) have shown that . . .

Subsequent citations: Both Jones, Corbin, and Fromme (2001) and Jones, Oeltmann, et al. (2001) produced similar results . . .

or

Subsequent citations: Both B. T. Jones, Corbin, and Fromme (2001) and S. E. Jones, Oeltmann, et al. (2001) produced similar results . . .

In these citations, because the lead authors are different, the lead author’s initials should be included in all text citations, regardless of how often they appear. In addition, there is no need to add the names of the additional authors to distinguish the two references on the second and subsequent citations because the initials before the surnames of the lead authors already accomplish that.

When to Use Author Initials for Text Citations

Tyler

 

 

by Tyler Krupa

You probably already know that references in APA Style are cited in text with an author–date system (e.g., Adams, 2012). But do you know how to proceed when a reference list includes publications by two or more different primary authors with the same surname? When this occurs, include the lead author’s initials in all text citations, even if the year of publication differs (see the sixth edition of the Publication Manual, p. 176). Including the initials helps the reader avoid confusion within the text and locate the entry in the reference list. For example, let’s look at the following two references and their corresponding text citations.

References

Campbell, A., Muncer, M., & Gorman, B. (1993). Sex and social representations of aggression: A communal-agentic analysis. Aggressive Behavior, 19, 125–135. http://dx.doi.org/10.1002/1098-2337(1993)19:2<125::AID-AB2480190205>3.0.CO;2-1

Campbell, W. K., Bush, C. P., & Brunell, A. B. (2005). Understanding the social costs of narcissism: The case of the tragedy of the commons. Personality and Social Psychology Bulletin, 31, 1358–1368. http://dx.doi.org/10.1177/0146167205274855

Text Citations

First citation: Many studies (A. Campbell, Muncer, & Gorman, 1993; W. K. Campbell, Bush, & Brunell, 2005) have shown . . . .

Subsequent citations: Both A. Campbell et al. (1993) and W. K. Campbell et al. (2005) provided participants with . . . .

As you can see from the examples above, even though the year of publication differs in the two Campbell references, the lead author’s initials should be included in all text citations, regardless of how often they appear.

Although this rule seems straightforward, one thing that trips up some writers is how to proceed when different lead authors with the same surname are also listed in other references in which they are not the lead author. To help illustrate what should you do, let’s look at the earlier Campbell examples again, but now let’s add some additional references.

References

Brown, Y., & Campbell, W. K. (2004).

Campbell, A., Muncer, M., & Gorman, B. (1993).

Campbell, W. K., Bush, C. P., & Brunell, A. B. (2005).

Smith, L. N., Campbell, A., & Adams, K. (1992).

Although you may be tempted to include the initials every time the surname Campbell appears in the text citations, note that per APA Style, the initials should be included only when Campbell is the lead author. Therefore, initials should be used for only two of the above four references in the text citations.

Text Citations

First citation: Many studies (Brown & Campbell, 2004; A. Campbell, Muncer, & Gorman, 1993; W. K. Campbell, Bush, & Brunell, 2005; Smith, Campbell, & Adams, 1992) have shown that . . .

Subsequent citations: . . . as was done in previous studies (Brown & Campbell, 2004; A. Campbell et al., 1993; W. K. Campbell et al., 2005; Smith et al., 1992).

Another related item to note is that if the reference list includes different lead authors who share the same surname and first initial, you should provide the authors’ full first names in brackets (see the Publication Manual, p. 184).

References

Janet, P. [Paul]. (1876).

Janet, P. [Pierre]. (1906).

Text Citations

(Paul Janet, 1876; Pierre Janet, 1906)

We hope these examples clear up any points of possible uncertainty. Still have questions? Leave us a comment.

Pluralize Numbers and Abbreviations Without Apostrophes

DB2



by David Becker

A common mistake people make is to include apostrophes when pluralizing a number or an abbreviation. Apostrophes are generally used in contractions and to indicate the possessive case, but they are not used to form plurals of numbers and abbreviations in APA Style.

For instance, writing “the 1960’s” when referring to that entire decade is incorrect; instead, one should write “the 1960s.” The same rule applies to the plural form of any other type of number, such as describing someone’s age (e.g. “clients in their 80s”), and is discussed further in section 4.38 on page 114 of the Publication Manual.

A similar rule in section 4.29 on page 110 applies to abbreviations. Just as with numbers, don’t include an apostrophe when pluralizing abbreviations. For example, when pluralizing an acronym, such as “CV” for “curriculum vitae,” all you need to do is add an s to the end, as in “CVs.” This rule also applies to standalone letters, as in “The students all received As.” For abbreviations that end with a period, such as “Ed.” to indicate an editor in a reference list entry, add an s before the period, as in “Eds.” When pluralizing an italicized abbreviation, remember not to italicize the s, as in “ps.” Just don’t add an apostrophe.

For more information, take a look at our other posts on punctuation in APA Style. Punctuation is also covered in more detail on pages 87–96 of the Publication Manual. And, of course, please feel free to comment on this post or contact us with any of your style questions.
